Volunteers put together 40 school-supply kits in 8 minutes. At this rate, how many could they put together in 30 minutes? Solve this problem using a unit rate.
To solve this problem using a unit rate, we need to find out how many school-supply kits the volunteers put together in one minute, and then multiply by 30 to find out how many they can put together in 30 minutes.
To find the unit rate, we divide the total number of school-supply kits (40) by the total time it took to put them together (8 minutes):
40 kits / 8 minutes = <<40/8=5>>5 kits/minute
So, the volunteers can put together 5 school-supply kits in one minute.
To find out how many kits they can put together in 30 minutes, we multiply the unit rate (5 kits/minute) by the total minutes (30 minutes):
5 kits/minute * 30 minutes = <<5*30=150>>150 kits.
Therefore, the volunteers can put together 150 school-supply kits in 30 minutes.
To solve this problem using a unit rate, we can first calculate the number of school-supply kits put together per minute.
40 kits / 8 minutes = 5 kits/minute
Now, we can use the unit rate to find out how many kits can be put together in 30 minutes.
5 kits/minute × 30 minutes = 150 kits
Therefore, volunteers can put together 150 school-supply kits in 30 minutes.
To solve this problem using a unit rate, we need to find the number of school-supply kits that can be put together in one minute.
Given that volunteers put together 40 school-supply kits in 8 minutes, we can find the number of kits put together in one minute by dividing the total number of kits by the number of minutes:
40 kits / 8 minutes = 5 kits/minute
So, the volunteers can put together 5 school-supply kits in one minute.
To find out how many kits can be put together in 30 minutes, we can multiply the number of kits put together in one minute by the number of minutes:
5 kits/minute * 30 minutes = 150 kits
Therefore, the volunteers can put together 150 school-supply kits in 30 minutes.
